Mastic, or Mastich, the Syrian Herb, or Marum Germander, Ttucrium Marum, L. 3 native of warm climates, and which we have incidentally mentioned, p. 369 of our second volume. Its leaves, distilled with water, yield a very acrid and penetrating essential oil, which resembles that obtained from scurvy-grass. And, though the plant is at present chiefly employed as a cephalic, there is reason to believe that it possesses very powerful diuretic and antiscorbutic virtues. Hence, Dr. Gleditsch strongly recommends an infusion of the leaves in wine properly digested, or a tincture prepared in proof-spirit, in diseases arising from relaxation of the solids, or a redundancy of viscid humours, such as lethargy, humid asthma, obstructions of the intestines, green sickness, swelling of the limbs, and the true scurvy. Being, however, an active medicine, the doses ought at first to be small, and but gradually increased ; for instance, from one to three table-spoonfuls of the vinous infusion ; or an equal number of tea-spoonfuls of the spirituous tincture should be taken, three or four times in a day.
